I recently learned that if A is a polynomial ring in Sage in variables x,
y, and z, the command
A({tuple([1,1,1]):1})
returns x*y*z.
Can somebody explain this syntax to me? I understand tuple([1,1,1]), but
what are the curly brackets and the colon doing?
Also, is there a reason that A.monomial([1,1,1]) does not return the same
result?
